Black/White > Black2/White2 because muh story and it does not hand feed you all the old Pokemon you have used in every game you have played before.
But if you're a pleb that don't give a shit about story in your shitty rpg and just want move tutor moves because muh competitive, then get BW2.
To be fair there are a lot of move tutor moves in BW2, but then again Hugh is almost as edgy and whiny as Silver was.
